ADTRAN-AOS-DNS-MIB

TEXTUAL-CONVENTION

Indicates which specific error condition occurred. Error codes 0-15 are the RCODE error codes, while 16-n are Adtran proprietary DNS Request error conditions. The noError(0) state indicates that there is no error condition. The formatError(1) state indicates that name server was unable to interpret the query. The serverFailure(2) state indicates that name server was unable to process this query due to a problem with the name server. The nameError(3) state indicates that the domain name referenced in the query does not exist. Meaningful only for responses from an authoritative name server. The notImplemented(4) state indicates that the name server does not support the requested kind of query. The refused(5) state indicates the name server refuses to perform the specified operation for policy reasons. For example, a name server may not wish to provide the information to the particular requester, or a name server may not wish to perform a particular operation (e.g., zone transfer) for particular data. The 6-15 states are reserved for future use. The unsuportedRCode(16) state indicates that the AOS unit does not support the RCODE (error condition) returned by the DNS sever. The malformedResponse(17) state indicates that AOS unit received an improperly formated data packet from the DNS server. The parseError(18) state indicates that AOS unit could not parse the data from the DNS server correctly. The timeoutWaitingForResponse(19) state indicates that AOS unit did not receive a response from DNS server in the predetermined waiting period. The emptyResponse(20) state indicates that the AOS unit received an empty response from the DNS server. Many DNS servers send responses without any answers as a form of failure. The unsupportedType(21) state indicates that the AOS unit does not support the qtype indicated in the DNS server's answer. The onlyRootAnswer(22) state indicates that the DNS server responded only with a '.' answer, the root domain. Per RFC2782 page 6, this is a failure. The portDeficiency(23) state indicates that the AOS unit failed to allocate an open port to send the DNS question to the DNS sever. The noServerConfigured(24) state indicates that the AOS unit does not have a DNS lookup server configured. The updSendError(25) state indicates that the AOS unit could not send the DNS question packet (maybe a routing issue with the configured name-server).
